The purpose of this paper is to study of the vehicle lamp manufacturing system composing ultra- sonic waves connection process. Making lamp assembly plant, it was produced in the separate process as the injection molding, ultrasonic waves bonding, annealing in the constant temperature, lamp assembling and packing. But the improvement method producing the lamp was added with one-step process by one automation technique. As a result, welding with ultrasonic waves process, the method decreased the energy consumption and noise during ultrasonic waves welding. Therefore, this method used the mathematics modeling for check- ing validity, it selected the stability and suitable controller using transfer function of plant and bode chart. In this study, the 180° revolution control system to turn injection part upside down was  because of grav- ity influence. It effected to unstable condition a system. For solving this problem, it aimed the linearization and stabilization of system by elimination  as applying Free-forward control technique.
